1、Designation: B 908 03 (Reapproved 2008)Standard Practice for theUse of Color Codes for Zinc Casting Alloy Ingot1This standard is issued under the fixed designation B 908; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This standard is published with the following objectives:1.2 To establish standard color codes for the Zinc DieCastin
3、g and Foundry industry, and1.3 To standardize the use and application of these colorcodes.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to become familiarwith all hazards including those
4、identified in the appropriateMaterial Safety Data Sheet (MSDS) for this product/materialas provided by the manufacturer, to establish appropriatesafety and health practices, and determine the applicability ofregulatory limitations prior to use.2.

Significance and Use4.1 The purpose of these color codes is to allow for quickidentification of ingot bundles or jumbo ingots of zinc castinga
9、lloys. Other than jumbo ingots, this standard is not intended toimply that each ingot will be color-coded but only that eachingot bundle be color coded.4.2 Each ingot bundle or jumbo ingot shall be identifiedwith the appropriate color code listed in Table 1.4.3 The color will be applied as a stripe,
10、 or stripes, on twoadjacent sides of the ingot bundle or jumbo ingot. The colorstripes will be applied to include the ingot bundle foot.4.4 When using multiple stripes, the colored stripes will beapplied from left to right as indicated in Table 1.4.5 In the absence of a written agreement to the cont
11、rarybetween the supplier and end user, the North American colorcode will be the standard for all North American transactions;for all other transactions the International Color Code will beused.5.
